본 발명은 자동차용 와이퍼 장치에 관한 것으로서, 더욱 상세하게는 구동암을 구동축 상단으로 위치시켜 모터축과의 높이 차를 줄여 와이퍼 장치의 떨림 및 소음 문제를 개선하고, 구동축과 구동암을 감싸는 방수 구조를 설치하여 피봇부의 누수 문제를 개선한 자동차용 와이퍼 장치에 관한 것이다. The present invention relates to a vehicle wiper device, and more particularly, by positioning the drive arm to the top of the drive shaft to reduce the height difference with the motor shaft to improve the vibration and noise problems of the wiper device, the waterproof structure surrounding the drive shaft and the drive arm The present invention relates to a wiper device for automobiles, which improves the problem of leakage of the pivot part.

일반적으로, 자동차의 윈드실드 글래스(windshield glass)에는 우천시에 시야를 확보하거나, 윈드실드 글래스에 쌓인 먼지나 오물을 제거하기 위해 윈드실드 글래스를 닦아 내는 와이퍼 장치(wiper system)가 설치되어 있으며, 와이퍼 모터를 작동시켜 윈드실드 글래스의 표면을 닦아 내는 경우에는 와셔액을 윈드실드 글래스에 분출시켜 와이퍼블레이드의 이동을 원활하게 하고, 윈드실드 글래스 상의 오염물질을 깨끗이 제거하게 된다. In general, windshield glass of automobiles is equipped with a wiper system for wiping the windshield glass to secure visibility in rainy weather or to remove dust and dirt accumulated on the windshield glass. In the case of wiping the surface of the windshield glass by operating the motor, the washer liquid is sprayed on the windshield glass to facilitate the movement of the wiper blades and to remove contaminants on the windshield glass.

통상, 자동차용 와이퍼 장치는 도 3에 도시된 바와 같이, 동력을 발생시키는 모터부(100)와, 동력을 전달하는 링크부(200)와, 윈드실드 글래스를 닦는 와이퍼블레이드부(300)로 이루어져 있다.In general, as shown in FIG. 3, an automobile wiper device includes a motor unit 100 for generating power, a link unit 200 for transmitting power, and a wiper blade unit 300 for wiping the windshield glass. have.

이때, 상기 모터부(100)의 와이퍼 모터(110)는 회전을 감속하는 기어케이스가 일체로 되어 있고, 직권계자 코일 및 분권 계자 코일의 전류를 변환함으로써 와이퍼블레이드(330,340)를 저속과 고속으로 작동시키게 된다.At this time, the wiper motor 110 of the motor unit 100 is integral with the gear case to reduce the rotation, and operate the wiper blades (330, 340) at low and high speed by converting the current of the series coil and decentralized field coil Let's go.

상기 링크부(200)는 대부분 좌우의 와이퍼블레이드부(300)를 연동시키는 기구로 되어 있는 바, 종속 링크(210)와, 윈드실드 글래스 하단 좌측 및 우측에 각각 결착된 지지 플레이트에 설치된 좌측 및 우측 구동축(230,240)과, 상기 좌측 및 우측 구동축(230,240)의 하단에 연결된 구동암(250,260)과, 상기 구동암(250,260)을 연결하는 전달 링크(220)로 구성되어 있다.Most of the link unit 200 is a mechanism for interlocking the left and right wiper blades 300, and the left and right sides are provided on the subsidiary links 210 and the support plates respectively attached to the lower left and right sides of the windshield glass. Drive shafts 230 and 240, drive arms 250 and 260 connected to lower ends of the left and right drive shafts 230 and 240, and transmission links 220 connecting the drive arms 250 and 260, respectively.

상기 와이퍼블레이드부(300)는 상기 링크부(200)의 좌측 및 우측 구동축(230,240)에 각각 연결되는 좌측 및 우측 와이퍼 암(310, 320)과, 상기 좌측 및 우측 와이퍼 암(310, 320)의 일단에 탈장착 가능하게 결합되어 상기 윈드실드 글래스와 접촉하는 고무 재질의 와이퍼블레이드(330,340)로 이루어져 있다. The wiper blade 300 may include left and right wiper arms 310 and 320 connected to the left and right drive shafts 230 and 240 of the link unit 200, and the left and right wiper arms 310 and 320, respectively. It is made of a wiper blade (330, 340) of rubber material which is detachably coupled to one end and is in contact with the windshield glass.

상기와 같이 구성된 자동차용 와이퍼 장치에 있어서, 보행자가 자동차와의 충돌 사고로 후드에 충돌시 보행자의 머리가 와이퍼 장치의 와이퍼 모터(110)에 직접 충돌하는 것을 방지하기 위하여 모터부(100)를 하향시키고 구동축(230,240)에 노치를 주어 보행자가 후드와 충돌시 와이퍼 장치가 쉽게 파손되도록 하여 운전자의 상해치를 줄이도록 되어 있다. In the vehicle wiper device configured as described above, in order to prevent the pedestrian's head from directly colliding with the wiper motor 110 of the wiper device when the pedestrian collides with the hood due to the collision with the car, the motor unit 100 is downward. And the notch is given to the drive shafts 230 and 240 so that the wiper device is easily damaged when the pedestrian collides with the hood, thereby reducing the driver's injury value.

그런데, 이러한 와이퍼 장치는 모터부(100)를 하향시키는 동시에, 링크부(200)를 구동축(230,240)의 하단에 위치시킴으로서 모터축(120)이 구동암(250,260)보다 과다 상향되므로 상기 모터축(120)과 전달 링크(220)를 연결함에 있어 큰 경사각 및 과도 꺾임 현상이 발생하며, 이로 인하여 링크부(200)의 소음 및 진동의 원인이 되며, 또한 와이퍼 블레이드(330,340)의 떨림 및 소음 등을 발생시켜 닦임성을 저하시키는 원인이 된다. However, such a wiper device lowers the motor unit 100 and simultaneously positions the link unit 200 at the lower ends of the drive shafts 230 and 240 so that the motor shaft 120 is excessively higher than the drive arms 250 and 260. When the 120 and the transmission link 220 is connected, a large inclination angle and excessive bending occurs, which causes noise and vibration of the link unit 200, and also causes vibration and noise of the wiper blades 330 and 340. It is a cause of deterioration of wiping property.

또한, 상기 피봇부 내로 빗물이 침투하여 작동이 되지 않는 현상이 자주 발생하는 문제점이 있다. In addition, there is a problem that often the phenomenon that the rain water penetrates into the pivot part does not operate.

따라서, 본 발명은 상기와 같은 문제점을 해결하기 위해 발명한 것으로서, 모터축과 구동암과의 높이 차에 의한 문제점을 개선하기 위하여 상기 구동암을 구동축의 상단으로 위치시켜 모터축과의 높이 차를 줄임으로써, 상기 모터축과 와이퍼 링크와의 경사각을 제거하는 동시에, 구동암의 꺾임 현상을 방지하며, 특히 구동축의 빗물 침투로 인한 작동 불량을 개선하기 위하여 구동축과 구동암을 감싸는 방수부재를 적용하되, 상기 구동축과 방수부재의 체결부는 나사결합 구조를 적용함으로써, 빗물의 누수 문제를 원천적으로 방지할 수 있는 자동차용 와이퍼 장치를 제공하는데 그 발명의 목적이 있다.
Accordingly, the present invention has been invented to solve the above problems, in order to improve the problem caused by the height difference between the motor shaft and the drive arm to position the drive arm to the top of the drive shaft to increase the height difference between the motor shaft. By reducing the angle of inclination between the motor shaft and the wiper link, at the same time to prevent the bending of the drive arm, in particular to apply a waterproof member surrounding the drive shaft and the drive arm in order to improve the poor operation due to rainwater penetration of the drive shaft.
